Abstract
In various embodiments, the present invention provides joint communication and sensing (JCAS) for in-band full duplex (IBFD) communication, wherein the transmitting device performs transmission of superimposed data and radar signals while simultaneously receiving a data signal. A self-interference cancellation process is additional implemented either in parallel with a conventional SI cancellation scheme or in series with a SI cancellation stage that handles multipath components.

A method for in-band full duplex (IBFD) radio communication, the method comprising:
- transmitting a superimposed communication and sensing signal from a transceiver;
- receiving, from another transceiver, a communication signal at the transceiver while substantially simultaneously transmitting the superimposed communication and sensing signal from the transceiver, wherein transmitting the superimposed communication and sensing signal and receiving the communication signal from the other transceiver utilize the same time and frequency resources of the transceiver;
- receiving a reflected superimposed communication and sensing signal at the transceiver;
- performing waveform separation of the reflected superimposed communication and sensing signal at the transceiver to extract;
- a sensing waveform and a communication waveform from the reflected superimposed communication and sensing signal;
- and
- a communication waveform from the communication signal received from the other transceiver.
